Two sister products, Sonar and Sonar Image, have been discontinued. Sonar Image functionality can now be achieved using Acrobat to scan and OCR documents into a PDF format and then using Sonar Professional to search and display the PDFs.

A free demo version of Sonar Professional is available on Virginia Systems' web site at: www.virginiasystems.com under "Downloads."

Sonar Professional costs $495 for a single-user license. Volume discounts are available.

Updates to Sonar Professional is free to users who had previously purchased Sonar Professional after February 1, 2010. Otherwise, a one-year support agreement that includes updates is $295. Support agreements can be purchased on the Virginia Systems' web site under "Ordering."
